I think this comment is from `static` and was included by me. Looks like it was part of the print styles moved across in https://github.com/alphagov/static/commit/ec39efc2869bcbe899795b2aefac73f0e68f1b14, originally taken from [whitehall](https://github.com/alphagov/whitehall/blob/25ec181b51d7aa29b44d2467bffeb0887a6b386a/app/assets/stylesheets/frontend/print.scss#L17).

Either way, the comment is now way out of context.
